Relieve Physical Strain via Manual Support

If the vehicle reports a communication loss or latch error during Supercharging, perform the following steps to verify if mechanical weight is the root cause:

  1. Insert the Supercharger handle firmly into the vehicle charge port until the latch clicks into place.
  2. Manually lift and support the weight of the heavy charging cable near the handle to eliminate downward torque and sagging on the port pins.
  3. Maintain this upward support for 10–15 seconds while the vehicle completes the high-voltage DC handshake and begins the charging ramp-up.
  4. If the charging session initiates and stabilizes while the cable is supported, the error is confirmed to be caused by mechanical strain; ensure the cable is positioned to minimize weight stress on the port for future sessions.
